MACHINE FOR DYElNG COTTON, 84,0.

SPECIFICATION forming part of Letters Patent No. 415,889, dated.November 26, 1889.

- Application filed July 1, 1889.

To all whom it may concern.-

Be it known that I, LEONARD XVELDON, of rhnsterdam, in the county ofMontgomery, in the State of New York, have invented new and usefulImprovements in Machines for Dyeing Cotton and Analogous Materials, ofwhich the following, taken in connection with the accompanying drawings,is a full, clear, and exact description.

The purpose of this invention is to thoroughly and evenly dye raw cottonstock in an economical and expeditious manner; and it consists in thecombination, with the rotary dipping cylinder or cage, of bars extendedthrough the interior of the said cylinder or cage in such positions asto cause the cotton to fall upon said bars, and thereby break up anddistribute the partially-wetted clods during the rotation of the dippingcylinder or cage, all as hereinafter more fully described, andspecifically set forth in the claims.

In the annexed drawings, Figure 1 is a front elevation of adyeing-machine embodying my invention. Fig. 2 is a vertical transversesection on line :2: as, Fig. 1. Fig. 3 is a vertical longitudinalsection on line y 11 Fig. 2. Fig. 4 is a vertical transverse section online 5 2', Fig. 1; and Fig. 5 is a detached transverse section of amodification of the breakenbar.

Similar letters of reference indicate corresponding parts.

A" represents the vat in which to deposit the dye-liquor, and O is therotary dipping drum or cage, which is journaled in suitable bearingssecured to the top portions of the end walls of the vat, and hasattached to its shaft, at the outside of the vat, a pulley P, by whichto transmit rotary motion to said drum. The peripheral wall of the drumis perforated, and the interior of the drum is divided into separate anddistinct longitudinal compartments by perforated longitudinal partitions'a a a, which are extended tangentially from a cylinder 0, arranged inthe drum concentric with the axis thereof, and rigidly secured thereto,said partitions forming acute-angled pockets 1) b in the portions of thecompartments adjacent to the periphery of the drum, for the purposehereinafter explained. Each of the compartments of the drum is providedwith a door d in the periphery of the drum for introducing and removingthe cotton.

Serial No. 316,142. (No model.)

Longitudinally through each compartment is extended a bar 6, which isarranged at or near the center of the compartment or in other suitableposition to effectthe purpose hereinafter explained. Said bars, which Idesignate breaker-bars, may be of any suitable shape in cross-section,and may also be armed with laterally-project-ing pins or wings, asrepresented in Fig. 5 of the drawings, and I prefer to pivot them to theheads of the drum 0 and extend one of the journals of each through oneof the heads of the drum, and at the outside of the latter I rigidlyattach to said journals either friction rollers or pinions Z Z, whichtraverse a segmental track or rack or, which is arranged above the vatconcentric'with the axis of the drum and firmly secured to a breast D,which rises from the top of the vat.

The operation of my improved dyeing-machine is as follows: Thedye-liquor being deposited in the vat A and the cotton introduced intothe compartments of the drum D and the doors d (Z (Z thereof closed, thedrum is set in motion, which is in the direction indicated by arrows inFig. 2 of the drawings. During themotion of the drum the cotton in thecompartment which rises from the vat falls into the acute-angled pocketof said compartment adjacent to the periphery of the drum, owing to thetangential disposition of the partition a, and hence the cotton iscarried the maximum distance through the dyeliquor. In passing over thetop of the vat elevated compartments traverse the track a, and therebycause the said bars to revolve. The cotton falling out of theacute-angled corners or pockets 1) b of the compartments strikes therotating bars 6 e, which break up the lump of cotton and distribute thecotton in its descent, and thus allow the dye-liquor to thoroughlypermeate the cotton and uniformly dye the same.

I do not limit myself to the use of a single bar 6 in each compartmentof the drum C, as it is obvious that two or more such bars may bearranged in-each compartment.

\Vhat I claim as my invention is- 1. In combination with the vat A, therotary drum 0, divided into separate and distinct compartments andperforated to admit the dye-liquor, and breaker-bars e e, extendtherollers or pinions Z Z of the bars 6 c in the.

ing through the central portions of the compartments, as and for thepurpose set forth.

2. In combination with the vat A, the rotary drum 0, formed with thecentral cylinder 0 and tangential partitions a a a, extending from saidcylinder to the periphery'of the drum, dividing the latter into a seriesof sep arate and distinct compartments, and the breaker-bars e 6,extending through the central portions of the compartments,substantially as described and shown.

In combination with the vat- A, the rotary drum C, divided into separateand dis-.

tinot longitudinal compartments, the rotary breakerbars e 6, extendedlongitudinally through the central portions of said compartments andpivoted to the heads of the drum, and having their journals extendingthrough one of said heads, pinions on the LEONARD VELDON. [11.Vitnesses:
